Vegas Pro 15 GPU render

Hello, I have a problem with GPU rendering. I have followed every guide/video I could find. I have enabled GPU rendering in my settings. I can use the NV encoder, but my GPU is always around 0% usage during rendering (meanwhile I see people taking it to 50%+)... My GPU is Geforce GTX 1070 by Gigabyte, CPU is i3 - 2100 and I have 8GB RAM.

I gave up on Vegas GPU integration long ago. I have better performance and a stress free workflow
leaving everything GPU out of my edits and turning it off in Vegas completely, Leaving all focus to
CPU Processing and the betterment of such.
